We have just applied secondary indexes to a very large ODS object in our Production environment. The system allows me to save the changes to the ODS, however, when I try to activate the ODS object, it is timing out. I assume this is because the system is creating the indexes upon activation. How do I activate the ODS object in the background? Since the original activation timed out, do I need to do any cleanup before attempting to activate the ODS in the background? Any help is very appreciated.
